Cord blood cells are collected in the umbilical cord at birth and can produce all of the blood cells in the body. They can be used to treat blood-related diseases, such as leukemia, lymphoma, sickle cell anemia, and others. Cord blood cells can also treat people whose bone marrow has been injured by chemotherapy or radiation. During treatment, these cells are injected into the bloodstream. Once there, doctors hope that they will make new, healthy blood cells.
Cord blood cells hoped will become treatment for all sorts of diseases in the future, such as Alzheimer’s, diabetes, and other conditions. They hold advantages over other types of stem cells. Umbilical cord blood stem cells are considered the ‘freshest’ and ‘youngest’ stem cells available.
They also avoid the ethical debate surrounding embryonic stem cells because cord blood cells do not involve the destruction of an embryo. In addition, cord blood stem cells hold an advantage over adult stem cells because they do not have the DNA mutations that the ‘older’ adult stem cells may have developed over time.
How are these cord blood cells collected? These will explain about that. To collect it, it is safe and simple for both mother and child. Exactly after birth, the umbilical cord is clamped and cut, and the baby is passed off to a pediatrician.
After collecting cord blood cells, a doctor or nurse uses a sterile solution to wash a small area of the umbilical cord that is still attached to the placenta. Then he or she will stick a needle into the cord’s umbilical vein. The blood will flow by gravity through the needle, through a tube, and into a collection bag.
The whole process takes a few minutes. Collecting cord blood cells is not always possible. For instance, if there are any problems with the delivery, either for the mother or child. The doctors will want to focus on resolving them instead of taking the cord blood.
Moreover, since collecting cord blood cells is not regular, you will need to set up the procedure with the hospital in advance. Experts recommend that you contact the cord blood bank by your 34th week of pregnancy.
After collection cord blood cells, the blood is shipped to a storage facility and frozen. It is not identified how long cord blood cells stay viable after cry preservation. Studies have shown the long-term survival of stem cells in cord blood stored up to 15 years. The viability of cry preserved them outside this time has not been confirmed.
The different stem cells are also in bone marrow, the spongy substance inside larger bones that makes your body’s blood cells. Both types of stem cells are called hematopoietic progenitor cells (HPCs). These cord blood cells can be injected into a sick person to replenish the supply of platelets and red and white blood cells. But early study indicates that someday these HPC cells may also be able give rise to other types of cells used in different parts of the body.
HPC stem cells are totally dissimilar from embryonic stem cells, which come from human embryos or fetuses. Embryonic stem cells can provide rise to many more types of cells, but since their use involves destroying embryos, the ethics of embryonic stem cell research is hotly debated.
